SPECIFICATION forming pari; of Letters Patent No. 313,030, datedFebruary 2-, 1885.

(No model.)

To @ZZ whom it may concern:

Be it known that I, J Aims F. SULLIVAN, of Fitchburg, in the county ofWorcester and State of Massachusetts, have invented a certain newanduseful" Improvement in Vater- Motors, ofwhich the following is adescription sufficiently full, clear, and exact to enable any personskilled in the art or science to which said invention appertains to makeand use the same, reference being had to the accompanying drawings,forming a part of this specilication, in which- Figure l is anisometrical perspective view of my improved motor in position for use;Fig. 2, a vertical longitudinal section of the same; Fig. 3, a verticaltransverse section; Fig. 4, a view of one of the lubricating-boxes withits cap removed, and Fig. 5 a vertical transverse section of one ofthefloats or buckets.

Like let-ters ot'reference indicate corresponding parts in different'figures ofthe drawings.

My invention relates to that class of watermotcrs which are designedmore especially for light work,where but little power is required, suchas running sewing-machines, coffee-mills, small lathes, che.; and itconsists in a novel construction and arrangement of the parts, ashereinal'ter more fully set forth and claimed.

The nature and operat-ion of the improvement Will be readily understoodby all conversant with such matters from the following` explanation.

In the drawings, A represents the case or body ofthe motor, and B thelegs' or supports in which the body is mounted.

Journaled horizontally in the body A there is a shaft, C, carrying onits outer end the pulley D, and within the case a thin metallic disk orannular plate, E.

Disposed at regular intervals around the periphery of the disk E, andattached thereto by rivets z, there are a series of buckets, H. Thesebuckets have narrow bottoms d, inclined sides m, and an inclined rearpartition- Wall,f, being open at their outer ends to discharge thewater, and are provided at their inner ends, behind the partition f,with a longitudinal slot, w, into which the edge of the disk E isinserted, as shown in Fig. 3. The periphery of the disk is cut ont atregular intervals, as shown by the dotted lines i in Fig. 2, to receivethe buckets and form the shoulders h, on which they rest, the upper sideof each ofthe buckets atits inner end bearing against studs Z, whichproject laterally from the disk E. A chamber, J, is formed on one sideor edge of the case A, into which the nozzle K ot' the induction-pipe Lis sc rewed. l

Passing laterally through the chamber J and nozzle K there is astop-cock or plug-Valve, M, 'provided at its outer end with a lever, N,adapted to be connected with a treadle or any other suitable device bywhich it may be actuated to open and close the nozzle. The shaft C isnot disposed at the center ofthe case or body A, but stands at one side,and preferably abovethe central axial line, thereof, as best seen inFig. 2, the object of eccentrically journaling the disk E being toprevent the reaction of the water on the interior of the ease oppositethe mouth ot the induction pipe or nozzle from interfering with the freerevolution of the disk. The buckets are so arranged on the disk and thedisk so journaled in the case, that as the disk revolves the bucketswill be presented at right angles, or nearly so, to the stream enteringthrough the nozzle, thereby utilizing the force ofthe water to the bestadvantage. The diameter of the ease nearly or quite twice as great asthat of the disk, and hence the water, after acting on the buckets, willpass almost directly out of the case through the eduction-pipe P,instead of being carried around bythe buckets and formingcountercurrents,which tend to retard the free revolutions of the disk,as in soine other motors of this character.

Disposed beneath either ofthe hubs or boxes Q in which the shaft C isjournaled, there is a lubricating-chamber, R, lled with wicking, T, orsome other good absorbent for the oil or lubricating compound; andleading upwardly from each of these chambers there are two ducts, c,communicating with the boxes Q in which the shaft or axle C isjournaled, these ducts being each provided with a strand of wickingadapted to carry the oil by capillary action from the chamber R t-o thebox, and thereby keep the shaft constantly and properly lubricated. Anannular groove, t, is cut in either box Q near its outer end, and lead-IOO ing downwardly from each of these grooves between the ducts c intothe interior of the case A there is a duct or drip-pipe,` a, the

grooves acting to catch the water,which tends to pass outwardly on theshaft C as the motor operates, and the ducts or pipes to conduct it backinto the interior o1" the case.
